I got a handful of ginkos from a freind who'd gathered them as weeds.
Thanks, Kyle, if you're reading this.
Since they're all little thin things without much foliage, I've
decided to conduct a scientific experiment on thickening trunks, since
I have no idea what works best. The first ginko i've planted in an 8 in
square pot (the rest are in 4 inch round pots). Admittedly, it was the
thickest one of the lot. the second one i'll flex every time I water
(i have too much time on my hands) The next one I was going to scarify,
on another I'll try the pins idea. That's four. I have three more that
I could use ideas on.
Although, since they grew as weeds, they've got foliage only on the top
third, no sacraficial branches availible. They're actually more like
sticks with leaves on top. They're all between 20 and 28 cm tall, with
trunks half a centimeter or less. (see why I want to try this?) I'll
measure them every week. Any suggestions on alternate techniques would
be appreciated. I'll keep everyone posted!
